Chapter: The marriage of the Prophet (saws) with Khadija رضي الله عنها and her superiority
(20)
بَاب تَزْوِيجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَدِيجَةَ وَفَضْلِهَا رَضِيَ اللَّهُ عَنْهَا

Narrated `Aisha:

I did not feel jealous of any of the wives of the Prophet (ﷺ) as much as I did of Khadija though I did not see her, but the Prophet (ﷺ) used to mention her very often, and when ever he slaughtered a sheep, he would cut its parts and send them to the women friends of Khadija. When I sometimes said to him, "(You treat Khadija in such a way) as if there is no woman on earth except Khadija," he would say, "Khadija was such-and-such, and from her I had children."

حَدَّثَنِي عُمَرُ بْنُ مُحَمَّدِ بْنِ حَسَنٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا حَفْصٌ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ مَا غِرْتُ عَلَى أَحَدٍ مِنْ نِسَاءِ النَّبِيِّ صلى الله عليه وسلم مَا غِرْتُ عَلَى خَدِيجَةَ، وَمَا رَأَيْتُهَا، وَلَكِنْ كَانَ النَّبِيُّ صلى الله عليه وسلم يُكْثِرُ ذِكْرَهَا، وَرُبَّمَا ذَبَحَ الشَّاةَ، ثُمَّ يُقَطِّعُهَا أَعْضَاءً، ثُمَّ يَبْعَثُهَا فِي صَدَائِقِ خَدِيجَةَ، فَرُبَّمَا قُلْتُ لَهُ كَأَنَّهُ لَمْ يَكُنْ فِي الدُّنْيَا امْرَأَةٌ إِلاَّ خَدِيجَةُ‏.‏ فَيَقُولُ إِنَّهَا كَانَتْ وَكَانَتْ، وَكَانَ لِي مِنْهَا وَلَدٌ‏.‏
